Final answer:
To solve the equation 4/5 = x/25, cross-multiply to find that x equals 20. This algebraic operation is a high school-level mathematics problem.
Step-by-step explanation:
The equation 4/5 = x/25 is a basic proportion that can be solved by cross-multiplication to find the value of x. By multiplying both sides by 25, you get 4/5 * 25 = x, which simplifies to x = 20. Therefore, the solution to the equation is x = 20. This type of question involves solving for unknown variables and is a fundamental concept in algebra, which is often taught at the high school level.
The given equation is (4)/(5)=(x)/(25). To solve this equation, we can cross multiply. Cross multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa. Therefore, we have (4)(25) = (5)(x). Simplifying this equation, we get 100 = 5x. Dividing both sides by 5 gives us x = 20. So, the value of x that satisfies the equation is 20.
